HP Application Recovery Manager software Integration guide (March 2008)

IMPORTANT:
After instant recovery, restored filesystems are mounted to the same mount points or
drive letters as they were at the backup time. If these mount points or drive letters have
other filesystems mounted, these filesystems are automatically dismounted before instant
recovery, and the restored filesystems are mounted afterwards.
Restore Using HP StorageWorks Disk Array XP
This type of restore can be performed if a backup was created with the XP provider
in the resync mode.
With this type of restore, the XP integration agent (SSEA) synchronizes an S-VOL with
its P-VOL and then splits the pair during the restore.
If the option Wait for the replica to complete is selected, SSEA waits for the
re-synchronization or copy process to complete (normal restore). Only then, the source
volume is available. If this option is not selected, the source volume is immediately
available while the re-synchronization or copy process is running in the background
(quick restore).
IMPORTANT:
The old source volume is not retained after restore so if the restore session fails the original
application data is lost.
HP StorageWorks Disk Array XP considerations
• Restore depends on the XP hardware provider mode which was used during
backup. If the VSS compliant mode was used, you can restore your data only
using VDS. If the resync mode was used, you can restore your data only using
HP StorageWorks Disk Array XP.
• You can switch between the XP hardware provider modes between different
backup sessions using the same backup specification, but this is not recommended
if the specified number of replicas rotated is more than 1 because restore will fail
in the following situations:
• If you perform a backup in one mode and then the same backup in the other
mode, restore of the backup performed in the VSS compliant mode (the "switch
of disks" restore) will fail because the relationship between the S-VOL and its
